I am on an issue since a while, getting urgent, and not super confident in the Windows sphere. I have a desktop at work that functions as my test desktop. To try software, etc, I installed Hyper-V and runs VM's on it containing the software. I'd like then to contact to those services (be it SSH or web) via my work laptop on which I do the actual work. I try to connect to them via SSH over port forwarding, but always get a timed-out error. I can connect to the VM via the Hyper-V host. I can not ping the machine but this is something that is "normal" based on my local IT. Thank you, cheers.
I have a VM with a running OpenSSH instance. This can be tested by SSH'ing from the Hyper-V host into the VM:
Hyper-V Host
PS C:\Users\u0130210> ssh -p 2023 [email protected]
[email protected]'s password:
You can also already see the ports I used for port-forwarding on the Hyper-V host. You can see two ways how I did the port-forwarding, as different tests to get it to work.
PS C:\> netsh interface portproxy show v4tov4
Listen on ipv4: Connect to ipv4:
Address Port Address Port
--------------- ---------- --------------- ----------
10.34.182.46 8083 172.27.41.98 8083

0.0.0.0 2023 172.27.35.147 22
The listen-on ports are also authorized in the Windows Firewall:
PS C:\> Get-NetFirewallPortFilter |
>> Where-Object { $_.LocalPort -eq 2023 } |
>> Get-NetFirewallRule

But from the remote laptop, I can not connect to it: Remote laptop

I also see nothing appear on Wireshark on the Hyper-V host. Maybe I use it wrong, but I filter on the physical ethernet port with filter: "tcp.port == 2023 || tcp.port == 22"
I am unsure what else needs to be done. Let me know if you need more information. I asked our local IT and there should be no external firewall in between both machines. They are even on the same switch.
Both IP's are on the same subnet:
Hper-V Host: 10.34.182.46/21
Laptop: 10.34.177.213/21
